Vespasian Æ Diobol, 8.85g Alexandria mint, 69-70 AD Obv: ΑΥΤΟΚ ΚΑΙΣ ΣΕΒΑ ΟΥΕΣΠΑΣΙΑΝΟΥ; Head of Vespasian, laureate, r. Rev: LΒ; bust of Isis, r. RPC 2420 (8 spec.). Acquired from CGB.fr, September 2020. This diobol struck in Vespasian's second regnal year features a bust of the goddess Isis wearing a headdress of cow horns enclosing a sun disk. The cult of Isis was very popular during the First Century and was given a particular boost by the Flavians, likely owing to Vespasian's lengthy sojourn in Alexandria prior to his arrival in Rome. Tellingly, Vespasian and Titus's joint triumphal procession of 71 at Rome started near the Temple of Isis where they had spent the night, a good indication of how important the Isis cult was to the Flavians. I think it's no accident this ethnic type was chosen as a standard reverse design for Vespasian's Alexandrian bronzes. Show off your coins featuring Isis!
